BAFFLE FOR `WATERT`UBE 'BOILER Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed March 11, 1908. Serial No. 420,342.

Be it known that I, LEO WOERNER, a citizen ofthe United States, residingat St. Lotus, in the State of Missouri, have invented a certain new anduseful Batlle for Watertubes.

One object of my invention `is to so construct the members of .which thebattle is formed that the balile will be lighter in weight than thoseheretofore'in general use,

so as to obviate 'the liability of springing the tubes, and also to soconstruct the members that any individual member can be readily placedin position or removed without removing the adjacent members. Anotherobject of my invention is to so construct the members that the bafHe maybe made to extend throughout the entire length of the tier of tubes andat the same time to properly direct the flow of gases among the tubes.

In the accompanyin drawings which illustrate one form of ba e made inaccordance with my invention, together with a portion of watertubeboiler to which the same is applied, Figure 1 is a verticallongitudinal section through the boiler and furnace; Fig. 2 is anenlarged cross section of a portion of the tubes and Fi 3 is a top planView.

Like marks o reference refer to similar parts in the several viewsin thedrawings.

5 represents the front wall, 6 the rear wall and 7 the fire wall vof thefurnace.

8 is the fuel chamber and 9 the combustion chamber, the former beingsituated between the walls 5 and 7 and the latter between the walls 6and 7.

Resting upon the front and rear walls 5 and 6 are the front and rearwater legs 10 and 11respectively, of the boiler. ing between the waterlegs 10 and 11 are the usual water tubes 12. Applied to the upper andlower tiers of the tubes l2 are the batlles Extendu 1 3. These baffles13 are each composed of two forms 'of tile members 14 and 15. The tilemembers 14 are substantially semi-cylindrical in form so as to fitaround the tubes 12 in pairs, as best shown in Fig. 2. The lower edges16 of each pair are in contact, as best shown in this figure, while theu per edges -17 are separated so as to allow of the partial rotation of`one of the membersaround the tube without disturbing the position ofthe other member. members 14 is provided with a laterally extending rib18 which is arranged somewhat above the center of the member and extendsthroughout the entire length of the member. rlhese ribs 1'8 are soproportioned that each 'bears against the corresponding rib of theadjacent member and so locks the parts :Of Vthe bale inposition aroundthe tubes 12. The members `l5 diHer from the members 14 only'in beingprovided with a rib 19 which instead 'of-extending along the entirelength of the member only extends through a very short portion of thelength. The ribs 19 lock the members 15 in position in the same' manneras the ribs 18 lock the members 14. Each of the members 14 and 15 isprovided, preferably just below the rib or projection 18 or 19, with anopening 2O for the insertion of a suitable tool for the rotation of theymember. y

The baffle 13 upon the lower tier of tubes has its forward end extendingover the grate chamber 8 composed ofy the members 14, while a portion ofthe rear .end over the combustion chamber 9 is composed of the members15. The entire length of the tubes is thus protected and the products ofcombustion are revented from passing up through the orward end of thetubes but are allowed to pass up between the tubes at .the rear .end. Inthe upper batllel the position of the members 151s reversed, bein placedat the forward end of the tier o tubes in place of at the rear end. Whenit is desired to remove one of the members it is rotated partially aboutthe tube, as shown at the central portion of Fig.4 2, and the adjacentpair of members are thus freed so that they may be rotated around thetubes and removed.

It will be seen that with my form of battle the members arecomparatively'light in weight and not liable to bend the tubes,

and that the entire length of the tubes isI Each of the protected and atthe same' time the products of combustion are properly guidedbetween thevarious tubes.

vHaving fully described myA invention, what I claim as new and desire tosecure by Letters Patent of the United States, is:

1. The combination with water tubes for boilers, of a bathe for saidtubes composed of members the bodies of which are substantiallysemi-cylindrical, each member being provided with an integral laterallyeX- tending rib, each rib having a convex surface and being adapted toengage with the rib of an adjacent member to lock said members inposition around the tubes, said members being movable around the tubesto disengage said ribs.

2. The combination with water tubes for boilers, lof abaffle for saidtubes composed of members the bodies of which aresubstantiallysemi-cylindrical, each member being rovided with anintegral laterally eX- tendlng rib forming with the body an offset orshoulder, each rib having a convex surface and being adapted to engagewith the rib of. an adjacent member to lock said mem-v` bers in positionaround the tubes, said members bein movable around the tubes todisengage said ribs.

3. The combination with water tubes for boilers, of a balie for saidtubes composed of members the bodies of which are substancuasi tiallysemi-cylindrical, the bodies of each of said members being ofsubstantially uniform thickness throughout, each member being providedwith an integral laterally extending rib, each rib having a convexsurface and being adapted to engage with the rib of an adjacent memberto lock said members in position around the tubes, said members beingmovable around the tubes to disengage said ribs.

4, The combination with Water tubes for boilers, of a battle for saidtubes composed of members the bodies of which are subl stantiallysemi-cylindrical, the bodies of each of said members being ofsubstantially uniform thickness throughout, each member being providedat a point intermediate its edges with an integral laterally extendingrib, each rib having a convex surface and being adapted to engage Withthe rib of an adjacent member to lock said members in positionlaroundthe tubes', said members being movable around the tubes to disengagesald ribs.

In testimony whereof I have hereunto set my hand and affixed my seal inthe presence of the two subscribing Witnesses.

LEO WOERN ER.
